About Silver Haze

Silver Haze is a sativa-dominant hybrid originating from Skunk and Haze genetics. It produces tall plants with an open structure, aromatic terpene profiles and an energising head high. The strain performs well indoors and can be grown outdoors with careful timing, especially in regions with a short outdoor growing season. Growers value it for daytime use, creativity and a clear, focused sensation rather than heavy sedation.

Grow Difficulty:

Overall difficulty is moderate and rewards attention to feeding and training. In a short outdoor growing season growers must time the start carefully to avoid late-season rot and stress.

Flowering Time:

Indoor flowering typically completes in nine to eleven weeks. Outdoors it normally finishes by early October in favourable conditions.

Yield:

Yield is medium to high with good light and nutrients. Controlled indoor environments usually outperform a short outdoor growing season for total harvest weight.

Height:

Plants grow tall with long internodes and an open canopy. The structure suits topping and sea-of-green or screen training to manage vertical space.

Environment:

Silver Haze performs reliably indoors and can produce good results outdoors in Powys when started early. In Powys outdoor growers should protect buds from late-season rain and consider mobile cover options.

Climate:

Growing Silver Haze in Powys requires planning around a short outdoor growing season and the local humidity. Finish early where possible and use ventilation and covered space to reduce mould risk in a short outdoor growing season.

Common question Posted by Urbanseedbank Answered
Q
I only have a short season in Powys, can I grow Silver Haze outside?
A
Verified answer
Yes, if you start early and use vigorous seedlings or clones, but plan to protect plants from autumn rain and consider pots for mobility.
Common question Posted by Urbanseedbank Answered
Q
My buds look tight and damp, what now?
A
Verified answer
Increase airflow, remove affected leaves, and if rain is forecast move plants under cover to reduce rot risk.
Common question Posted by Urbanseedbank Answered
Q
Should I use SCROG for height control?
A
Verified answer
A SCROG works well to spread the canopy and control vertical stretch while improving light distribution.
Common question Posted by Urbanseedbank Answered
Q
What's the best flush practice before harvest?
A
Verified answer
Flush with plain water for 7-10 days if you use synthetic nutrients; for organic feeds a shorter flush may be enough.
Common question Posted by Urbanseedbank Answered
Q
Do you recommend coir or soil?
A
Verified answer
Good loam-based soil provides buffering and microbial life; coir gives control and faster growth but needs more precise feeding.
